The 'Voice' coaches recently struck up a relationship after both of their marriages ended this year and Behati, 26, - who is married to their co-star Adam Levine, 36 - admitted she was not surprised by the romance.

When asked by Andy Cohen on 'Watch What Happens Live' if she knew about their relationship before it became public, she said: "I didn't, but we kind of called it ahead of time just because they were both kind of going through a moment. They're so different but so perfect for each other, so I didn't know, but I felt it."

The pair started dating in November and Gwen, 46 - who has three sons, Kingston, nine, Zuma, seven, and Apollo, 20 months, with her ex-husband Gavin Rossdale - recently admitted she feels "so exposed" at times because of her new relationship but is "grateful" for the 39-year-old singer.

She said: "Everything changed so quickly like overnight. I'm so tongue-twisted right now - I don't like talking about it.

"I am embarrassed about it sometimes because I feel so exposed but I am so grateful for that friendship that saved me through this year. It's unbelievable what it takes to get through stuff."
